• Select desired application using rotary mode switch (1 … 10)
by turning up or down (see 5.3).
• Adjust drop-out delay (0 … 30 sec.) with rotary time switch
(16 increments) by turning up or down (see 5.3).
• After performing setting, close front cover again.
• Front cover can be secured with a lead seal to protect it from being
